Mid-Eocene (Bartonian) larger benthic foraminifera from southeastern Turkey and northeastern Egypt: New evidence for the palaeobiogeography of the Tethyan carbonate platforms

Dictyoconus aydimi (Gallardo-Garcia and Serra-Kiel, 2016) comb. nov., larger benthic foraminifera from the Middle-Upper Eocene of the Middle East (SE Turkey, Iraq, SW Iran, Oman): New evidence for Arabian Plate faunal provincialism

“…The Hoya Formation (~45-m-thick) consists mainly of cream-colored micritic limestones, alternating with partly dolomitic limestone beds at the lower and upper parts. Assemblages of LBF from this locality were reported by Özgen-Erdem and Sinanoğlu (2016) and Sallam et al (2018). The rich assemblages of LBF observed in the Hoya Formation are represented by alveolinids, soritids, and orbitolinids (Figure 2).…”

“…Paleocene taxa (e.g., Coskinon, Dictyoconus, Fallotella, Karsella) have been reported from the Taurides of Turkey (Province of Elazığ and Kars) (e.g., Sirel, 2015). Assemblages of middle Eocene (Bartonian) larger benthic foraminifera (LBF), including Orbitolinidae, have been studied from the Hoya Formation of SE Turkey (northeastern Diyarbakır), belonging to the northernmost part of the Arabian Plate (Özgen-Erdem and Sinanoğlu, 2016;Sallam et al, 2018). Large-sized dictyoconids previously referred to Dictyoconus aegyptiensis (Chapman), usually occur above limestones with Somalina stefaninii Silvestri, This form has been recognized as Rogerella aydimi described recently by Gallardo-Garcia and Serra-Kiel in Serra-Kiel et al (2016) from the middle-upper Eocene of Oman.…”

Contribution to the biostratigraphy of the Middle-Upper Eocene rock units at North Eastern Desert; an integrated micropaleontological approach

“…Minor shale beds encountered in G. Abu Shama whereas, the upper parts grade to hard, thickly bedded siliceous, fossiliferous limestone and chalky limestone. Although, the lower boundary of Observatory Formation is unexposed but the presence of pinkish nodular limestone at the base indicates unconformity which confirm the absence of Gebel Hof Fm in G. Abu Shama due to highly pulsating seismicity (Sallam et al., 2018). The observatory Formation conformably underlies the Qurn Formation, and commonly rich in LBF such as Nummulites beaumonti d’Archiac and Haime , Nummulites aff pulchellus (Hantken) , Nummulites thalmanni (Schaub), Rhabdorites minima (Henson), Pseudolacazina schwagerinoides (Blanckenhorn), Periloculina cf.…”

Geochemical assessment of carbonate and clay rocks for the cement industry: a case study from Gabal Akheider, Ain Sukhna area, north-west Gulf of Suez, Egypt

“…The deposits suitability was evaluated through petrographical, mineralogical, and chemical compositions and parameters. Many of the previous studies were focused on the stratigraphy, paleontology, facies, and sedimentary environments of the Middle Eocene Sannor (limestone) Formation (Boukhary and Abdelmalik, 1983;Said, 1990;Abu El Enain et al, 1995;Osman, 2003;El Azabi, 2006;Sallam et al, 2015Sallam et al, , 2018. Other studies concern tectono-sedimentary evolution and sequence stratigraphy of Middle Eocene carbonates (Tawfik et al, 2016).…”
